Famous quotes containing the word probability:

    “The probability of learning something unusual from a newspaper is far greater than that of experiencing it; in other words, it is in the realm of the abstract that the more important things happen in these times, and it is the unimportant that happens in real life.”
    —Robert Musil (1880–1942)
